Take it: Baked chips are not boring—witness Kettle Brand Bakes Potato Chips in Hickory Honey Barbeque. So much flavor! Popped chips, like the original, Popchips, are another great find. Look for single-serve bags to keep portions in check.

Take it: If you want some protein for long-lasting energy, jerky rocks. It's a great portable protein that's surprisingly low in fat. A 1-ounce serving can have around 80 calories and 3 grams of fat or less. I love the options from Jack Link's and Tillamook Country Smoker, especially the nuggets.

Take it: High-protein and high-fiber bars are all-around snack stars. Look for bars that have no more than 250 calories, like the Luna Protein or Fiber line, or a Kind Fruit & Nut bar.

Skip it: The Riblets Platter can run you up to 1,860 calories and 89 grams of fat. An average 150-pound woman would have to walk 20 miles to burn off the calories from that meal!

Order it: Anything off the Under 550 Calories or Weight Watchers menus. The bold flavors of the Roasted Garlic Sirloin (460 calories, 18 grams of fat) and the Weight Watchers Lemon Parmesan Shrimp (490 calories, 13 grams of fat) will satisfy even the most demanding, I'm-on-vacation taste buds.

At Subway…

Skip it: The Big Philly Cheesesteak is big on fat—17 grams, not to mention 500 calories. And don't even think about the cheesy Chicken & Bacon Ranch Melt, which is weighed down with 28 grams of fat and 570 calories. (And these numbers are for the 6-inch subs, people, not the foot-longs.)

Order it: Lean proteins and fresh veggies. Go for a protein-veg combo like a grilled-chicken salad (but ask for dressing on the side, and dip, don't pour). Or get the hot turkey platter (gravy on the side) with steamed veggies. Comfort food on the road—hold the guilt.
